Osteospermum plant named ‘Duetimhopi’

ABSTRACT

A new and distinct cultivar of  Osteospermum  plant named ‘Duetimhopi’, characterized by its compact, upright and mounded plant habit; freely branching growth habit; early and freely flowering habit; and daisy-type inflorescences with elongated oblong-shaped ray florets that are red purple in color.

Botanical designation: Osteospermum ecklonis.

Cultivar denomination: ‘DUETIMHOPI’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Osteospermum plant, botanically known as Osteospermum ecklonis, and hereinafter referred to by the name ‘Duetimhopi’.

The new Osteospermum plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the program is to create and develop compact Osteospermum plants with uniformly mounded plant habit and numerous attractive inflorescences.

The new Osteospermum plant originated from a cross-pollination conducted by the Inventor in July, 2006 of a proprietary selection of Osteospermum ecklonis identified as code number Q05-9686-006, not patented, as the female, or seed, parent with a proprietary selection of Osteospermum ecklonis identified as code number Q05-3010-503, not patented, as the male, or pollen, parent. The new Osteospermum plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Rheinberg, Germany in May, 2008.

Asexual reproduction of the new Osteospermum plant by terminal cuttings in a controlled environment in Rheinberg, Germany since May, 2008, has shown that the unique features of this new Osteospermum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Osteospermum have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Duetimhopi’. These characteristics in combination distinguish ‘Duetimhopi’ as a new and distinct cultivar of Osteospermum:

-   -   1. Compact, upright and mounded plant habit.     -   2. Freely branching growth habit.     -   3. Early and freely flowering habit.     -   4. Daisy-type inflorescences with elongated oblong-shaped ray         florets that are red purple in color.

In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Osteospermum differ primarily from plants of the parent selections in ray floret coloration.

Plants of the new Osteospermum can be compared to plants of the Osteospermum ecklonis ‘Mansa’, not patented. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Osteospermum differed primarily from plants of ‘Mansa’ in the following characteristics:

-   -   1. Plants of the new Osteospermum were broader than plants of         ‘Mansa’.     -   2. Plants of the new Osteospermum had larger inflorescences than         plants of ‘Mansa’.     -   3. Plants of the new Osteospermum and ‘Mansa’ differed in ray         floret color as plants of ‘Mansa’ had purple-colored ray         florets.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Osteospermum plant. This photograph shows the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Osteospermum plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Duetimhopi’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph, following observations and measurements describe plants grown in Rheinberg, Germany during the summer in a glass-covered greenhouse and under conditions and practices which approximate those generally used in commercial Osteospermum production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Measurements and numerical values represent averages for typical flowering plants. Plants were grown in 10.5-cm containers, pinched three weeks after planting and were 13 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
